The location principle of centroid localization is as follows: the unknown node sends broadcast messages to the network for determining its location information; after anchor nodes received broadcast messages, they sent response of information of its own location to the unknown node; the center of mass in this graphic is regarded as the estimation coordinate of the unknown node [17, 18], which is formed by anchor nodes.
It is a concrete application of centroid localization method; the location principle is as follows: there are any three anchor nodes that composed one triangle; there is a collection formed by all triangles which included the unknown node; the coordinate of the unknown node is determined by determining the center of mass of graphic which is composed of all triangles of the collection.
To this end, HP leverages partnership with local cloud service providers in the EMEA region, thus enforcing the national data
location principle until the new Data Protection EU framework is completed."
